Installing the Switch
Caution
Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a
suitable and safe earth ground before connecting them to the switch or other devices.
Caution
Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling
to connect Cisco prestandard IP Phones and wireless access points, IEEE 802.3af, or 802.3at (PoE+)-compliant
devices. You must remove any cable or device that causes a PoE fault.
